What does a bottom dance like and what does dancing have to do with a persons sexual preference in position? Answer: Nothing.

If anything the only things dancing does tell you is if the person is or isn't good in bed.

It would seem you are project, OP, without even realizing. I would say if your friend is a total top but dances like a bottom (so you) then you've just given him a compliment since most bottoms, or at least the ones I've seen and know, tend to be great dancers and know how to move their bottom which is also a good indication that they know what they are doing in the bed.

if you mean dance like your dancing it to Waka Flocka - No Hands or Ester Dean - Drop It Low....then absolutely 100% haha its fun and it gets the guy excited, plus if you do it on stage to be funny at school, people will go crazy cheering haha (trust me from experience)
